EXPEDITED PERMIT PROCESS FOR SMALL.SCALE PV SYSTEMS <br />STANDARD STRING SYSTEM <br />The information in rhis guideline is intended to help local jurisdictions and confractors identii/ when PV sysrem installations <br />are simple needing only a basic review and when an installation is more comple)(. It is likely that 50 % -75% of all residenrial <br />slstems will comply with these simple criteria. For projects that fail to meet the simple crireria. resolution sreps have been <br />suggested to provide as a path ro perrnir approval. <br />Requbed InJoflnation Jor Pennit: <br />1. Site plan showing location of major components on the property. This drawing need no( be exactly to scale, bur it <br />should represent relative location of components at site (see supplied example site plan). PV arrays on dlvellings <br />with a 5'perimeter space at ridge and sides may not need separate fire service review. <br />2. Electrical diagram showing PV array configuration, wiring system, overcurrent protection. inverrer disconnects, <br />required signs, and ac connection ro building (see supplied standard elecrrical diagram). <br />5. Specifrcation sheets and installation manuals (if avallable) for all manufacrured components including, but not <br />limited to, Pv modules, inverter(s). combiner box, disconnects, and mounting system. <br />Step 1 : Structural Review of PV Array Mounting System <br />Is the array to be mounted on a denned, permitt€d roof structure? E Yes E No <br />U No d.ue to non4ompliant rooJ or a gound mount, submit completed worhsheet lor the strucntre wRS I . <br />Roof Information: <br />I . ls the roofing tvpe lighrweighr (Yes = composition, lighrweighr masonry, meral, erc. ..)Yes, it is composite shingle <br />IJ No, submit completed worksheet lor rool sffucture LvfiSl (No = heavy mdsonry. slate, etc. . .) <br />2. Does the roof have a single roof covering? Elyes Eno <br />If No, submit completed worksheet for roof structure wRSl. <br />5. Provide merhod and type of weatherproofing roof penetrations (e.g. flashing. caulk)flashing and/or caulk <br />M ount ing Sy s t ern Inform at i on : <br />I . Is the mounting structure an ejgineered product designed to mount PV modules with no more than an 18" gap <br />beneath rhe module frames? lll yes LJ tlo <br />Il No, provide deta.ils of structural attachment certiled by a design proJessional. <br />2.

PV moddes, utility-interactive inveners, and comblner boxes are identihed for use in Pv systems. <br />2. The PV array is composed of 4 series strings or less per invener <br />5. The total inverter capacity has a continuous ac power output I 5,440 Watts or less <br />4. The ac interconne(ion poinr is on the load side of service disconnefiing means (690.64(8)). <br />5.
